I have a small piece of code which works perfectly when run as `julia tmp.jl` and even as `julia -e 'include("tmp.jl")'`, but not when I start `julia` and immediately type `include("tmp.jl")`! Neither it works if I just copy-paste the content of `tmp.jl` into fresh julia session.
Namely, it fails with `ERROR: LoadError: StackOverflowError:` without traceback. So I have no idea how to debug it further from the julia side.
The code uses `ccall` and `@cfunction` with `$closures` to call a C/Fortran library, so I inserted a bunch of `print`s there for debug. They indicate that the library fails to call a function passed from julia as `@cfunction`, and again not sure how to debug further.
Unfortunately, I cannot provide a simple self-contained example now, as it uses both julia and c/fortran libraries.

At least show us the Julia code. Are you sure there is no recursive call?

Completely sure. The code in `tmp.jl` is very short and everything it does is calling a library:
```julia
using LibProcessTmp
run_process(
callback = (a, b) -> a == b,
settings = Settings(size = 2),
)
```
I don’t see anything here to behave differently when run as a file and from repl. Also note, that the execution certainly goes into the library, and even into the wrapped C library, because I inserted prints there. And `@cfunction`s I talk about are defined in the library, not even in this `tmp.jl` file.

Sounds a bit like [Initialization of R fails on julia 1.1](https://discourse.julialang.org/t/initialization-of-r-fails-on-julia-1-1/19735/1)

Any idea how to debug this?
